The US Federal Reserve's decision to freeze interest rates contrary to expectations triggered a sharp decline in the US stock and bond markets. The Dow Jones Industrial Average recorded its largest drop in 15 months, while the yield on 30-year US Treasury bonds reached its highest level since 2007, raising questions about the Fed's commitment to fighting inflation. Experts analyzed that the bond market was sending a message demanding more aggressive inflation-fighting measures from the Fed. The international gold price rose by nearly 2%, and international oil prices also surged significantly due to concerns over escalating tensions between the US and Iran, amplifying anxiety.
